During the first years of his nearly two-decade tenure as the president of the American Federation of Musicians, James Petrillo was instrumental in organizing a strike of musicians that effectively halted the recording industry from 1942 to 1944. Concerned that juke boxes were severely undercutting live revenue for touring musicians -- and that recorded music would similarly replace live radio sessions for professional musicians -- the AFM went on strike, leading to no recording company recording a musician they had under contract, either as leaders or as support for singers. This two-year strike hurt the recording industry, and so when the threat of another strike surfaced toward the end of 1947 -- this time, the point of contention was distribution of funds to musicians losing work due to juke boxes and radio -- the labels decided to stockpile tons of recordings, just in case this second strike lasted as long as the first. It didn't. This second strike only lasted throughout 1948 and when it ended, many musicians wanted to record new material, leaving labels with a surplus of recordings that eventually trickled out over the years.
